UNITED STATES PATENT CHRISTIAN H. 'KOOK, OF AVOOA, IOWA, ASSIGNOB OF FOUR-FIFTHS TO RUDOLPH SEHMER, PETER XVIESE, J. J. HIPSLEY, AND F. A. XANTEN.

LUBRlCATOR FOR CAR-JOURNALS.

SPECIFICATION forming part of Letters Patent No. 315,638, dated April 14, 1885.

Application filed August 23, 1884.

To all whom it may concern.-

Be it known that I, CHRISTIAN H. Koox, a citizen of the United States of America, and a resident of Avoca, in the county of Pottawattamie and State of Iowa, have invented a Oar-Axle Lubricator, of which the following is a specification.

My object is to prevent the dangers, delays, and accidents and losses incident to the friction and heating of journals in operating railway-cars upon fixed tracks. 7

My invent-ion consists in the construction and combination of an anti-friction roller and lubricator with an axle-box and axle, as hereinafter fully set forth, in such a manner that it will revolve with the journal, and constantly convey lubricant matter from the chamber in the box to the journal while the car is in motion.

Figure 1 of the accompanying drawings is a longitudinal section of a car-axle box of common form, and also of my revolving lubricator placed under the journal that extends into the box. Fig. 2 is a transverse section of the same box, journal, and detachable roller and lubricator. Fig. 3 is a perspective view of my roller and lubricator and its elastic bearings and movable base. Jointly considered, these figures clearly illustrate the construction, application, and operation of my complete device.

A represents a car-axle box.

13 is a hinged cover over an opening at the outer end, through which 1 introduce my 111- bricating device and the lubricant.

O is a rectangular frame, and the base upon which my anti-friction roller is supported and carried.

D D are arched and elastic bearers attached to the ends of the frame and base 0 by means of screws passed through elongated perforations in the ends of the bearers and into the base, or in any suitable way, in such a manner that the roller placed upon them will rise (No model.)

J is a perforated cylinder, preferably made of sheet metal, retained in concentric position with the axle and its flanges by means of circular grooves formed in the inside faces of the flanges, or in any suitable way, in such a mannor that mineral wool, tow, or cotton can be retained within the perforated cylinder, to serve as a vehicle to carry oil from the chamber under the journal and apply it to the journal whenever the car is in motion.

K represents a porous covering, preferably made of asbestos, placed over the perforated cylinder J in such a manner that the entire outside surface of the roller will be even with the periphery of the flanges and in contact with the journal F, that projects over it, and by means of a collar, F", on its end prevents the roller from moving longitudinally.

L and L are brass plates placed upon the journal and under the roof of the box A in a common way.

In the practical operation of my lubricator thus constructed and applied, the caraxle journals constantly engage the rollers in the oil-chambers of the axle-boxes and revolve them when the car is in motion; and as the rollers are rotated they distribute oil through the perforations in the cylinders and their porous covering to the surfaces of thejournals, to keep them constantly wet with lubricant as required to diminish friction, and to prevent the journals from becoming heated and darnaged.

I claim as my invention- 1. A roller for distributing lubricants, composed of an axle having a fixed collar or flange at one end, a detachable collar at its opposite end, a detachable perforated cylinder, and a porous cylindencover, in combination with a car-axle box and an axlejournal, to operate in the manner set forth, for the purposes speci- 2. The lubricating device consisting of the roller H H H J K, a frame, 0, and elastic arched bearings D, in combination with a cara-xlebox and a journal, substantially as and for the purposes set forth.
